WebFor the 2 sides of your equation to be equal, the exponents must be equal. So, you can change the equation into: -2b = -b Then, solve for "b" Sal does something very similar at about 3:45 in the video. Hope this helps. 2 comments ( 15 votes) Upvote Downvote Flag more Sky7ure 6 years ago
Negative exponents (video) Khan Academy
WebWhen dividing exponential expressions with the same base where the base is a nonzero real number, copy the common base then subtract the top exponent by the bottom exponent. We must suppose here that b \ne 0 b = 0 and both m m and n n belong to the set of integers. Examples: Simplify the quotient of exponential expressions. WebJul 14, 2024 · When adding or subtracting with powers, the terms that combine always have exactly the same variables with exactly the same powers. These rules are true for multiplying and dividing exponents as well. Example 1: x + x + x = 3 x. Because the variables are the same ( x) and the powers are the same (there are no exponents, so the exponents … hustler turf parts manual
Solving a Formula For a Variable Contained in an Exponent
WebHowever, to use the division rule of exponents, you must use the same base. We can take the greatest common divisor of the different bases and make this our new base! 2^ (3*2) / 2^4 = 2^ (6 - 4) = 2^2 = 4 ( 4 votes) NABAAJASSAM2004 5 years ago can you teach step by step SLOWLY? • 3 comments ( 2 votes) Sara Lynn Younes 4 years ago WebDividing exponents with same base For exponents with the same base, we should subtract the exponents: an / am = an-m For example: 34 / 32 = 34-2 = 32 = 3⋅3 = 9 Dividing exponents with different bases When the bases are different and the exponents of a and b are the same, we can divide a and b first: an / bn = (a / b)n Advertisements For example: WebMar 26, 2016 · Distributing with negative exponents means that you'll have fractional answers. A base that has a negative exponent can be changed to a fraction. The base and the exponent become the denominator, but the exponent loses its negative sign in the process. You then cap it all off with a 1 in the numerator. hustler tv on spectrum
